Things We Do For No Reason #TWDFNR highlights some widespread practices that are difficult to justify based on lack of proven health benefits, but significant cost (both financial and non-financial harms). Avoid these low value practices and inflated medical bills with tips from expert, Dr Lenny Feldman, MD, FACP, Associate Professor of Medicine Johns Hopkins. Topics include: renal ultrasound and urine electrolytes in acute kidney injury (AKI), folate deficiency and anemia work-up, prealbumin and malnutrition, blood transfusions, shellfish and contrast allergies, monitoring after switch from IV or oral antibiotics, and “against medical advice” discharges.
